• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach ky) OR (sach ty)) hang tai hoi. hieu ve pham duc ban thanh ((san cua) OR (dan cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ky) or (sach ty)) hang tai hoi. hieu ve pham duc ban thanh ((san cua) OR (dan cua)) te".
